| What
is IP Telephony?
IP Telephony or VOIP
(Voice Over Internet Protocol) is the transmission of telephone calls
over a data network. This is accomplished by packetization of the voice
streams. VOIP enables users to make telephone calls over a data network
like the Internet. VOIP converts the voice signal from the telephone into
a digital signal that can be transmitted across the data network. At the
receiving end the signal gets converted back to voice. The basic telephone
functions between traditional voice and VOIP are identical. Users pick
aup the receiver, hear dial tone and dial numbers as they’ve done
in the past. In fact, many VOIP users are unaware that they are not on
a traditional PBX phone system until they learn about the additional features
and functions that an IP Telephony system provides.
What
are the benefits of IP Telephony?
IP Telephony may
use a single infrastructure for providing both Internet access (data)
and Internet telephony (voice). Only data-oriented switches need be deployed
for moving data as well as packetized voice.
By moving from two
separate networks to one powerful converged network, an IP Telephony solution
provides immediate cost reductions in both staffing and maintenance of
hardware and software.
The convergence of
voice and data may facilitate the implementation of such cutting edge
applications as unified messaging, multimedia conferencing, collaborative
contact centers, and interactive multimedia response systems. These applications
help organizations realize business gains by improving operational efficiencies,
increasing productivity, and enhancing both user and customer satisfaction.
IP Telephony Solutions
allow telecommuting employees to become more productive by granting access
to all the capabilities of the telephony software.
How
can IP Telephony save money?
One Network: IP Telephony
eliminates the cost and administrative overhead required for separate
voice and data networks. Why buy, support and manage two separate networks
when all you need is one?
Toll Bypass: Calls
between branch offices may take advantage of existing IP network connectivity
as opposed to paying for PSTN (Public Switched Telephone Network) calls
thereby saving money by routing long-distance calls over the IP network.
No branch office PBX:
The remote branch may be set up to appear as an extension to the main
branch, enjoying the same voice-mail, conferencing, and desktop handsets
as the central branch, but without deploying a local PBX to handle off-network
calls.
Lower Start-up Costs:
Deployment of new IP telephony services requires significantly lower investment
in terms of time and money than in the traditional PBX environment.
Quicker ROI: Investment
payback in most cases is usually achieved within 12-18 months following
installation.
What
are the components of an IP Telephony system?
IP Telephony systems
are composed of these basic elements:
- End devices: these
may be IP phones, traditional telephones and/or audio-equipped personal
computers.
- Gateways: handle
signal translations between traditional telephone equipment and IP network
devices.
- Gatekeepers/proxies:
the gatekeepers/proxies provide centralized call management functions
such as user location, authentication, bandwidth management, address
translation, etc.
There are so many vendors out there. How do I choose an IP Telephony system?
An IP Telephony solution
should be reliable, scalable, standards-based, and provide the features
and functionality that would meet your business needs.
Our customized systems
employ distributed architecture that eliminates dependency on any single
component for redundancy and reliability. And adding users or a new branch
office is easier and relatively inexpensive compared to a PBX-based system.

Would
an IP Telephony solution provide the features my business requires?
IP Telephony is the
most affordable voice solution in addition to offering a rich set of call-processing
features including voice mail, automated attendant, hunt/call groups,
call detail reporting, computer telephony integration, unified messaging,
and PC-based visual voicemail/e-mail clients that enable a peer-to-peer
relationship between a user’s phone and computer. By adding available
software to an audio-equipped PC, users can view recent calls, make calls,
access the system directory, even drag and drop telephone numbers from
other PC applications or web pages. Our customized systems easily integrate
with numerous off-the-shelf applications, including customer relationship
management (CRM), call centers, and speech recognition. Advanced applications
may also be added that will further enhance productivity.
Would
I be able to link branch offices?
Our customized systems
offer an extensive range of connectivity options to link branch offices
as well as support for remote access users and telecommuters.
How
could I introduce an IP Telephony solution to my existing PBX-based enterprise
without a major overhaul?
Some IP Telephony
solutions can seamlessly integrate with legacy PBX-based phone systems
and even legacy phone sets in order to provide a migration path to IP-based
telephony over time and at a rate that suits your business requirements.
What
is SIP?
The Session Initiation
Protocol (SIP) is a signaling protocol used for establishing sessions
in an IP network. A session could be a simple two-way telephone call or
it could be a multi-user/multi-media conference session. The ability to
establish these sessions means that a host of modern services become possible.
SIP is emerging as
the protocol of choice for setting up conferencing, telephony, multimedia
and other types of communication sessions on the Internet. SIP may also
be used for new types of communications, such as application-level mobility
across various networks, including wireless, and across user devices.
How does SIP work?
SIP is a request-response
protocol that closely resembles two other Internet protocols, HTTP and
SMTP (the protocols that run the world wide web and email). SIP transforms
telephony into just another web application and thereby facilitates easy
integration with other Internet services.
Rather than defining
a new type of addressing system, SIP addresses are much the same as an
email address.
SIP manages the following
basic communication functions:
- User location
- Session establishment
- Session participation
- Session feature
establishment
What
are the advantages of SIP?
SIP can establish
multi-user sessions regardless of media content. SIP achieves this by
the opening, modifying and closing of sessions over IP networks. These
sessions could be as basic as a telephone call or as complex as a multi-party
mixed media session.
SIP makes use of open
Application Programming Interfaces (APIs) where customized services may
be programmed and deployed that combine elements from telephony and other
web applications such as email, messaging, video streaming and the Internet.

on customized programming services for SIP-enabled phone systems, please
contact us at 800-988-1914.
What
are the components of SIP?
There are two basic
components within SIP: the SIP user agent and the SIP network server.
The user agent is the end system device such as a cell phone, PDA, multi-media
handset, or PC. The SIP server is the network device that handles call
signaling. The main function of the SIP servers is to provide name resolution
and user location, since the caller usually does not know the host name
or IP address of the called party.
I
don’t want to be a “Beta” site for an unproven technology.
Is SIP a standard?
Over the last couple
of years, SIP has been adopted as the protocol of choice for signaling.
SIP is an RFC standard (RFC 3261) from the Internet Engineering Task Force
(IETF), the body responsible for administering and developing the mechanisms
that power the Internet.
An ever-growing number
of carriers and ISPs are offering SIP-based services such as local and
long distance telephony, presence and Instant messaging, push to talk,
rich media conferencing, and more.
A wide variety of
SIP-enabled voice systems and phones are available that give consumers
flexibility of choice and cost.
How
can I tell if a SIP-enabled phone system is right for my business?
Choosing a phone
system for your business is a decision that cannot be make lightly. A
modern phone system must meet the following basic requirements. It must:
- Meet the specific
requirements of your business
- Scale to meet
future needs as your business grows
- Make maximum use
of 21st century features and functions
- Fit within budgetary
constraints
Only an experienced
vendor-independent dealer/integrator can advise you as to which system
is right for you and your business. And a full-service dealer/integrator
can design and implement the voice system, train your staff, and provide
ongoing support for any upgrades and/or repairs.
